WHILE CRUISING AT 4000 FEET, THE ENGINE QUIT. THE PILOT ATTEMPTED TO RESTART THE ENGINE, BUT FAILED. THE AIRPLANE CRSHED IN A ROCK PIT WHERE IT SUSTAINED MAJOR STRUCTURAL DAMAGE TO THE UNDERCARRIAGE. FUEL WAS IN BOTH TANKS WHEN EXAMINED AT THE ACCIDENT SITE. THE AIRPLANE EXAMINATION ALSO FAILED TO DISCLOSE ANY MECHANICAL PROBLEM WHICH WOULD HAVE PREVENTED NORMAL OPERATION. THE ENGINE OPERATED NORMALLY DURING THE FUNCTIONAL EXAMINATION. HOWEVER, THE ICING PROBABILITY CURVE INDICATED THE POSSIBILITY OF CARBURETOR ICE FORMATION. THE AIRPLANE WAS EQUIPPED WITH AN OPERATIONAL CARBURETOR HEAT SYSTEM.
Probable Cause: THE PILOT'S FAILURE TO USE THE CARBURETOR HEAT PROPERLY, WHICH RESULTED IN THE FORMATION OF CARBURETOR ICE, FOLLOWED BY A COMPLETE LOSS OF ENGINE POWER. FACTORS TO THIS ACCIDENT WERE CARBURETOR ICING CONDITIONS AND THE ROUGH AND UNEVEN TERRAIN AT THE CRASH SITE.
